Sayduck is a web-based 3D product visualization platform for ecommerce teams that publish products as interactive 3D viewers, configurable product experiences, web AR previews, and virtual product photography. Its workflow is built around a reusable product model: upload the asset, organize its scene, add materials and product options, then publish the result for use on a storefront or other web page.
Sayduck is the stronger choice for a merchant that needs an interactive product page, not simply a finished image. A prepared product model can become a browser viewer where shoppers rotate and zoom the item, select colors, materials, sizes, or components, and view supported configurations in AR. That makes it useful for furniture, home products, and other configurable goods where the customer needs to explore the product before buying. RENDERCAD serves the earlier and lighter-weight visual task: start with a CAD viewport, product screenshot, design image, or architectural view and turn that visible design into a polished still. It does not require web-ready mesh preparation, variant structure, an embedded viewer, or ongoing storefront configuration.
A Sayduck project begins with a 3D product asset rather than a screenshot. Teams upload a supported model, prepare the product scene, assign materials and textures, define the product options that should change, and publish an embeddable experience. The output can support interactive browsing, configurable products, web AR, and virtual product images, so the same underlying asset can be used across a commerce presentation. Asset quality and performance remain the source-of-truth boundary: the product geometry, material behavior, configuration rules, and storefront integration must be set up and maintained for the experience to represent the sellable product accurately.
RENDERCAD is useful when that full product-experience pipeline is unnecessary or not ready. Use a clear CAD viewport, design review image, product angle, or architectural screenshot as the starting view, then generate a refined visual for a concept review, catalog draft, pitch deck, listing mockup, or marketing direction. It is a practical route to still-image exploration while CAD and ecommerce teams continue to own the master model and product data. Use Sayduck for persistent interactive 3D and AR buying experiences. Use RENDERCAD for fast presentation renders from an existing visual reference; it does not replace Sayduck's configurable viewer, published product logic, or source product asset.
Screenshot the CAD viewport you already have, render in the browser, and download a client-ready still or video without exports, plugins, or GPU setup.

RENDERCAD uses a maintained selection of image-generation models for different rendering tasks. Results can vary by model and input, so compare generated output with the source design before relying on geometry, materials, or dimensions.
| Feature | RENDERCAD | Sayduck |
|---|---|---|
| Engine | Generative AI | Real-time WebGL 3D viewer, configurator, and web AR platform |
| Output | Images + Video | Embeddable interactive 3D viewers, configurable product experiences, web AR previews, and virtual product images |
| Resolution | HD / 4K | Viewer and image quality depend on model optimization, textures, scene setup, device, and embed context |
| Image Speed | Image renders complete in 60 seconds. | Real-time product interaction after the model, configuration, and published viewer are prepared |
| Video Speed | Videos complete in 2-5 minutes. | Not primarily a video production tool; viewer responsiveness depends on asset preparation, browser, and device |
| Scene Set Up | No separate local scene | Upload and prepare a product model, organize the 3D scene, assign materials, configure product options, and publish an embed |
| Input | Screen Snip | Prepared OBJ, glTF, or GLB product assets; CAD data usually needs conversion and web-focused preparation first |
| Materials | 2,600+ Textures | Materials, textures, colors, and product-option variations configured around the uploaded 3D asset |
| Backgrounds | 1300+ Backgrounds | Tool-dependent |
| Conditions | 40+ Effects | Tool-dependent |
| References | Up to 6 Per Render | Varies |
| Hardware | Cloud (None Required) | Cloud platform with web viewers that can be embedded on websites |
| Install | None | Cloud service with embeddable web viewers; site and ecommerce integration work depends on the storefront |
| Cost | from $9/mo | Commercial subscription service with options that vary by business needs |

Get StartedCommon questions about RENDERCAD and this workflow
Yes. A clear viewport capture can become a more polished visual for a design review. Image renders complete in 60 seconds, making it practical to prepare or iterate presentation options.
RENDERCAD is designed to create more polished, realistic-looking presentation images from a source view. Results vary by input and settings, and generated images should be checked against the original model before they are used to communicate exact design details.
Upload a clear view, describe the brushed-aluminum finish you want, and add a material reference when the visual direction matters. Because the result is generated from an image, inspect the grain direction and surface details against your original design before using it in a final presentation.
Describe the wood species and finish you want, and provide a reference image when scale or grain direction matters. RENDERCAD can generate a wood-like visual treatment, but it does not replace model-level texture mapping or guarantee an exact, repeatable grain pattern.
Start with a clear source view, choose a simple background, and describe the studio look you want. RENDERCAD can generate a presentation image without requiring you to build a traditional light rig, but the lighting is image-based and should be reviewed rather than treated as a physically measured setup.
Yes. Request a golden-hour look and describe the mood or direction you want. The generated warmth, shadows, and light direction can vary between results, so compare important design details with the source image.
The Seamless Loop option is designed to improve continuity between the end and beginning of a generated video. Inspect the transition before publishing because generative motion and loop quality can vary by image and model.
RENDERCAD's Create Video workflow generates a video from a single image and provides Camera and Product Motion controls. Videos complete in 2-5 minutes.
RENDERCAD image renders complete in 60 seconds. Competing real-time tools may preview quickly, but final output speed still depends on scene complexity, hardware, export settings, and output quality.
Usually. Generation runs in the cloud, so it does not occupy a local renderer. Keep the relevant browser workflow available as required, and expect normal network and browser resource use while the job is submitted and results are loaded.
RENDERCAD starts from a supported 2D image such as a CAD viewport capture, product photo, or drawing. You do not need to import the native 3D scene, but you may need to capture or export a clear image from the source application first.
RENDERCAD avoids much of the scene, shader, and local-renderer setup used by traditional rendering tools. Users still need to prepare a useful source image, choose suitable options, describe the intended result, and review generated details.
